Beginner's Guide to ArcGIS Desktop

Introduction

• ArcGIS Desktop is a widely-used GIS software across various sectors (health, transportation, water resources, geological sciences, etc.).
• The tutorial is divided into four parts and aims to cover ArcGIS Desktop's functionalities through practical applications.
• By the end of the tutorial, users will know the available tools, how to use them, and complete relevant tasks efficiently.

Tutorial Structure

2. Working with Vector Data
3. Working with Raster Data
4. Creating Standard Maps

Overview of ArcGIS Desktop

Main Components

• ArcMap: Primary application for GIS data usage (geoprocessing, editing datasets, creating maps, etc.).
• ArcCatalog: Used for organizing and managing GIS data (like Windows Explorer but for GIS data).
• ArcScene: 3D visualization of geospatial data.
• ArcGlobe: Viewing GIS data on a 3D globe surface.

ArcMap User Interface

• Toolbars: Standard Toolbar and Tools Toolbar can be moved.
• Table of Contents: Visualize layers and structure geospatial information.
• Panels: Catalog and Search panels for quick data access and tool searches.

Working with Vector Data

Types of Vector Data

• Point Data: e.g., banks.
• Polyline Data: e.g., rivers.
• Polygon Data: e.g., regions of interest.

Attribute Table

• Contains data associated with vector features (e.g., names of banks, attributes of rivers).
• Very useful for quick selections and data organization.

Styling Vector Data

• Change appearance, size, and color of vector features.
• Add labels using the attribute table information.
• Use Identify Tool for quick information access.

Geoprocessing Tasks

1. Clip Tool: Extracts specific areas from input features using another feature as a boundary.
   • Example: Clipping rivers using a region of interest.
2. Intersect Tool: Identifies common areas between multiple layers.
   • Example: Common areas between two regions of interest.
3. Union Tool: Combines areas together to form a single shapefile containing unique and common areas of input features.
   • Example: Combining two regions of interest.
4. Dissolve Tool: Merges features based on common attributes to reduce data complexity.
   • Example: Merging river segments based on river name.
5. Buffer Tool: Creates buffer zones around features based on specified distances.
   • Example: Creating buffer zones around rivers or regions of interest.
